Background
Lithium is increasingly used in our lives and is in increasing demand, with the use of the battery field increasing in demand.
Among upstream manufacturers of lithium battery manufacturers, it is necessary to extrude a lithium raw material into a strip-shaped lithium strip, then roll the lithium strip into a disk shape, and then package the disk-shaped lithium strip to supply the lithium strip to downstream manufacturers.
In the process of manufacturing the lithium belt, metal lithium is placed in a pipeline, a mould is arranged at the head end of the pipeline, a strip-shaped opening is arranged on the mould, then a pressing rod is jacked into the pipeline from the tail end of the pipeline, the metal lithium is pushed in the pipeline, and when the metal lithium moves to be in contact with the mould, the metal lithium is extruded and output from the opening of the mould, so that the lithium belt is formed.
The metallic lithium has certain viscosity, and can not contact with water, and can react with water to generate corresponding hydroxide and hydrogen.
The pipeline that extrudes the lithium area possesses the extrusion section, and the front end of extrusion section is connected with the cooperation section, is provided with the internal thread in the cooperation section for with mould connection.
After the lithium strip extrusion process is carried out for a period of time, metal lithium remains on the inner wall of the extrusion section, the metal lithium forms a plaque-like structure, the metal lithium adheres to the inner wall of the extrusion section, and after the metal lithium is accumulated to a certain extent, the next and subsequent lithium strip extrusion processes can be adversely affected, so that the quality of the manufactured lithium strip is affected, and after the lithium strip is produced for a period of time, shutdown is needed to remove the plaques.
Meanwhile, because the die and the matching section are matched with each other inevitably with gaps, and the matching section is pressed greatly in the extrusion process, after the lithium strip extrusion process is carried out for a period of time, a small amount of metal lithium is extruded into the inner wall of the matching section and remains in the inner wall of the matching section, the inner wall of the matching section also forms a structure similar to plaques, the inner wall of the matching section is stuck on the inner wall (internal thread) of the matching section, and after the inner wall is accumulated to a certain extent, the next and subsequent die installation are adversely affected, so that shutdown is also needed after the production is carried out for a period of time, and the plaques are cleared.
The plaque cleaning method is manually stripped or wiped, the efficiency of the plaque cleaning method and the plaque cleaning method is low, residual metallic lithium is easy to exist, the stripping method is easy to damage the inner wall of a pipeline, meanwhile, the plaque cleaning method cannot be used for cleaning with water, the operation of a production line can be influenced due to the fact that the pipeline is required to be dried after cleaning, and the scrapping of a large number of products can be caused due to unqualified water drying.
